Fixes the following security issues:
- CVE-2021-28902: In function read_yin_container() in libyang <= v1.0.225,
it doesn't check whether the value of retval->ext[r] is NULL. In some
cases, it can be NULL, which leads to the operation of
retval->ext[r]->flags that results in a crash.
- CVE-2021-28903: A stack overflow in libyang <= v1.0.225 can cause a denial
of service through function lyxml_parse_mem(). lyxml_parse_elem()
function will be called recursively, which will consume stack space and
lead to crash.
- CVE-2021-28904: In function ext_get_plugin() in libyang <= v1.0.225, it
doesn't check whether the value of revision is NULL. If revision is NULL,
the operation of strcmp(revision, ext_plugins[u].revision) will lead to a
crash.
- CVE-2021-28905: In function lys_node_free() in libyang <= v1.0.225, it
asserts that the value of node->module can't be NULL. But in some cases,
node->module can be null, which triggers a reachable assertion (CWE-617).
- CVE-2021-28906: In function read_yin_leaf() in libyang <= v1.0.225, it
doesn't check whether the value of retval->ext[r] is NULL. In some cases,
it can be NULL, which leads to the operation of retval->ext[r]->flags that
results in a crash.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
